Duration 4 hours; see the effect

You construct a small explosive device. You, or another creature holding the device, can use an action to throw the device to a point within medium range. When the device reaches that point or impacts against a solid surface before then, it explodes in a 3-yard radius, dealing 2d6 damage to everything in the area. A creature in the area can make an Agility challenge roll. A creature also becomes blinded for 1 minute on a failure, or it just takes half the damage on a success. When the device explodes or the duration expires, the spell ends.
